Let's divide 680155 by 90
We want to figure out the number of times 680155 can be divided by 90.

Going ahead to step 1:
90 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 90

On to step 2:
If we divide 68 by 90, we get 0 and a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 68 leaves us with 68.
Bring next digit (0) of the dividend behind the 68 and repeat the process: 680 / 90

Advancing to step 3:
680 divided by 90 is 7 with a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 630 from 680, we get 50.
Fetch the next digit (1) from the dividend, attach it to 50 and continue: 501 / 90

Moving on to step 4:
90 can be fit into 501 5 times, resulting in a remainder of 51.
Record the quotient 5 as the next digit in the result. 
Result so far: 75.0
If we take 450 away from 501, we end up with 51.
Grab the next digit (5) from the dividend, add it to 51, then carry on: 515 / 90

Advancing to step 5:
When dividing 515 by 90, we get 5 with a remainder of 65.
The next digit of our result is 5. 
Result so far: 755.0
The remainder is 65 after subtracting 450 from 515.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 90

Step 6:
When dividing 655 by 90, we get 7 with a remainder of 25.
Put 7 as the next digit of the answer. 
Result so far: 7557.0
Subtract 630 from 655 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 7:
90 can be fit into 250 2 times, resulting in a remainder of 70.
Record the quotient 2 as the next digit in the result. 
Result so far: 7557.2
Deduct 180 from 250 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
700 divided by 90 is 7 with a remainder of 70.
Use 7 as the next digit of our solution. 
Result so far: 7557.27
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
The number 7 becomes the next digit in our result. 
Result so far: 7557.277
The remainder is 70 after subtracting 630 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final result is 7557.277 with a remainder of 0.007.
